Popupmenu positioned too low

[smolck]

I think the popupmenu should be a little closer to the cursor here, it seems a bit too low:

I think I've figured out the problem, here's the line that causes it:

goneovim/editor/popupmenu.go

Line 226 in 01a0c51

y := row*p.ws.font.lineHeight + p.ws.font.lineHeight + p.ws.tabline.widget.Height()

The problem is that p.ws.tabline.widget.Height() is added to the y value of the popupmenu regardless of whether the GoNeovim external tabline is enabled. Thus, when disabled (as I have it) the popupmenu is moved farther down than it should be.

Thus, to fix it we only need to check if the tabline is enabled or not, and if it isn't then don't add the p.ws.tabline.widget.Height() value to y.
